UNITED sTATEs rATENT oEEIcE. FREDERICK C. WAR-NE, OF MANSFIELD, OHIO,ASSIGNOR TO*THERODIllRICK` LFAN MANUFACTURING COMPANY, 0F MANVSFIELD,OHIO, A CORPORATION OF-NEW JERSEY.

To all whom t may concern:

Be it known that I, FREDERICK C. WAENE, a citizen of the United Statesof America, residing at Mansfield, in the county. of Richland and Stateof Ohio, have invented certain new and useful Improvements 1nCultivators, of which the following 1s a specication.

My invention relates to cultivators of the balanced type.

The objects of my improvement are to provide a cultivator with means toequally balance the frame and the beams carrying shovels forward and inthe rear of the axles preparatory to operating the shovels of the beamsin the soil or lifting them out of working position; to provide means ofsustaining the beams in their inoperative posi.-

tion without manual assistance; to provide means of keeping the beamsand frame 1n balance during the time the shovels are being forced topenetrate the soll more or less in the cultivating operation; to providemeans of increasing or decreasing the lifting power of the balancingmechanism; to provide means of relieving the weight on the neck of theanimal in transmitting the pull to the cultivator and preventing thepole from vibrating or flying up; to provide means of neutralizing thebalancing mechanism to permit the beams to be operated withoutresistanceand independent ofthe balancing mechanism.

Having these and other objects in view,y

my invention consists of the parts and combination of parts, ashereinafterdescribed and more particularly pointed out in the claims atthe end of this specification.

In the accompanying drawings, Figure is a perspective view of a walkingcultivator to which my invention is applied. F is a side view of thebalancing mechanism showing one of the beams in full lines neutralposition preparatory to being operated and in dotted lines in operativeposition. Fig. 3 is an end view of Fig. 2. Fig. 1 is an enlargedfragmentary4 detail view.

Referring to the drawings, reference numerals 1 and 2 indicate parts ofa yoke which are connected together and arranged` to be adjustedlaterally if desired. To the outwardly projecting bentends of the yoke,clamping brackets 3 and l are securely attached, extending in a rearwarddirection. Axles 5 and 6 are securely attached to the Specification ofLetters Patent.

free ends of the vbrackets and wheels 7 and- 8 mounted thereon. A pole 9is secured to the yoke by the brackets 10 and carriesv a `bitchingdevice 11. Sleeves 12 and 13 which Iare provided with cranks 15 and 16(pref-- gerab-ly made in the form of a sector) are journaled on theoutwardly projecting bent ends of the yoke. Coupling members 17 and 18embrace and are rigidlyV secured to the sleeves in any well known mannerpreferably by being keyed thereto as shown.y .The connecting couplingmembers 19 and "2O are attached to the extremitiesv of the Ibeams A andB and provide connecting 'means between the coupling members 17 and 18and the sleeves. Bars 21 and 22 are pivoted to the side members of theyoke leav- Qing their free ends extending on each side fthereof.Swinging bars 23 and 24 having their lower ends curved are piv-``gotally and removably supported on bolts 25 and 26iwhichj are carriedby the'forwardly extending ends of the pivot bars 21 :and 22. Ihe curvedends of the bars 23 and 2a are pivotally connected to the sector cranksat the forwardly extending radii thereof with reference to the axisofthe bent ends of the yoke members. The rear- "wardly extending endsofthe pivotal bars 21 and 22 are provided with apertures to receive theadjustable bolts 27 and 28 and -are connected to coil springs29 and 30.

Link bars 31 and y32 are connected to one end of the coil springs andvto the rearwardly extending radii of the sector crank with reference tothe vaxis of the bent ends ofthe yoke member. The sector .cranks areprolvided with a series of apertures C. y

I will now describe the loperation of the balancing device but will onlydescribe the operation of one beam and its connecting mechanism as itwill be understood that both beams and their connecting mechanism arevexact duplicates of each other in structure as well as operation andfunction.l

, Especial attention is now called toFig. 2 of the drawings. y'When thebeam A is in the position shown in full lines, the tension of thespring; 29and the .weight of the beam A and itsiattachments aresubstantially equalized or what may be called neutral, that is,

the weight of the beam and its attachments are counterpoised by thetension of the,

spring. Vhen the beam A is raised by the operator to the position shownin dotted lines, vthe sleeve yl2 `is Vpartially revolved 'carrying thesector crank rearwardof'the' aX'is 'of the bent"l end of the yokemembery uponwhich it is mounted in the direction? of the spring and itsconnections, the swinging bars, the spring and its connections to thesector crank landpivotal bar 2l Aare then' free fromresistance and'permit'the' spring to exert-its tension to liittand maintain the f id.beamy and its attachments in inoperative po-` sition, as l.shown indottedlines.
